By way of explanation, it maybe stated that even with the most, improved means for changing a tire on an automobile wheel, when the tire goes flat, tire-changing is a dirty and time-consuming job, requiring not only the loosening of the nuts but requiring, as well, the useof a jack and much workunder or about a car. The; foregoing being .iinderstood, it may be stated that thisi'nventioh Ff) aims to providea simple but efi'ective means (whereby anauxiliary wheel may be assembled with a main wheel whichhas a'llat tire,

simply by placing theauxiliarywheel against the main wheel and driving away in yehicle, there being no occasion for loosenm bolts, taking out ajack, and resorting to a l i of the operations commonly necessary in connection with ajflat tire, i

It is within the province of the disclosure to improve generally and to enhance the utilsity of devices of that ventionappertains;

'NVith the above and otherobjeets in view, which" will appear as the/ descriptioniprotype to which th ceeds, the invention'resides in the combination and arrangement of ,part'sand' in the details of construction hereinafter described.

and claimed, it being understood that changes in the precise embodiment of the invention 1% herein disclosed, may he made within the scope of what is claimed, without departing from the spirit of the invention.

The human 1 marks the body of a wheel on an automobile, and this wheel may cenveni'ehtly be referred to as the main wheel. Although, for simplicity in explaining the invention, the ,wheelbody llias been shown in the form his disk, it will be understood adisli wheel, 'aiidthat it can be used on a Wheelof any known construction. The wheel body 1 "carries; a' piieumatietire 2.

Oh the 'wlieelbody 1, there are outwardly projecting brackets 3.. The bracket-s13 are:

U-shaped, as shown in Figure 2, arid open toward thfc'entrj of the wheel, In the outer portions of the brackets 3, there are holes 4. The wheel bodyl carries anou'twardly bracket.

' n The device cd'prises an auxiliary whee-1,

the body of which isde'sigiiatecl by the m1- iner'al 6, The wheel they 6 is shown in the has been explained hereinbefore, in connection with the wheelbody 1, and the auxiliary wheel t ey 6 hear any desired onstruetion. on the wheel body 6 is insulate atir'e he has alei-gs when opshih s iqsstsd hpposite the has-esp of the main w en.

To theysideof theauzgiliary wheel body 6 is secured an inwardly pihjsstihg' bracket 9, and in the bracket 9 is secured atransverse ,pivot element 10, such as a pin; Figure t .shows that in the inner endof the pin there is a transverse recess, in; which' latcheslll are The latches 11 are pressed outwardly by a spring 12-carri-ed by s the outer end portion of the pivot pin 10, and

the spring causes the inner endsof the latches 11 to engage stops 14 mounted on the pivot pin, within the recess. The" latches ll-are provided with bevelled edges 15',- leading backwardly to transverse shoulders 16. The

wheelvbody 6 carries inwardly projecting steamers 17, which bra cl'r tsahounted on the rim" ofthe wheel body, or eleswheif. Inspeetion openings 18" are formed" in the projecting shoulder 5, which may be an angle the; the invention is by he means eonfiii'ed to than of a disk, but a disk is not necessary, as

Lou

wheel body 6, adjacent to the shoulders or brackets 17.

Resilient, circumferentially extended latches 19 are secured to the wheel body 6 and have holes 23. Each of the latches 19 is provided with a loop-shaped seat 20, and each latch has an end 21 which is inclined away from the wheel body 6, as Fig. 3 will show. The wheelbody 6 has openings 22 located adjacent to the ends 21 of the latches 19, and giving access thereto.

Suppose that the tire 2 on the main wheel body 1 goes flat, as shown in Figure 1. Then the pivot pin 10 on the auxiliary wheel body 6 is inserted into the opening 4 of the bracket 3 on the wheelbody 1 which is placed most conveniently with respect to the ground, the tire 7 on the auxiliary wheel body 6 resting on the ground, as shown in Figure 1, in eccentric relation to the main wheel. As the pin 10 is inserted into the opening 4 of the rack et 3, the latches 11 move inwardly and then swing outwardly to the position of Figure 4, under the action of the spring 12, the pivot pin 10 being held in the bracket 3 against withdrawal, as shown in Figure 2.

When the automobile is started, the tire 7 on the auxiliary wheel 6 rolls on the ground,

the fiat'tire 2 of the main wheel is lifted off the ground, and the wheels move into concentric relation to each other. As the wheels move toward concentric relation to each other, the latches 19 on the wheel body 6 engage with the brackets 3 on the wheel body 1 which are not connected to the pivot pin 10 on the wheel body 6, the said brackets are received in the seats 20 of the latches 19, and the wheels are held together, in concentric relation, all of the weight being taken oil of the flat tire 2. As the wheels arrive at concentric relation, the shoulder 5 on the wheel body 1 comes in contact with one of the shoulders 17 on the 'wheel body 6,'to form apositive abutment.

In order to disengage the latches 19 from the brackets 3, a suitable tool (not shown) may be inserted through openings 22 in the wheel body 6.

The device is simple in construction, and it affords an eilicient means whereby time and labor may be saved when aflat tire occurs, the devlce being of utility to anyone who wishes to save time, or to avoid the soiling labor incident to changing a tire on the road accordingto known methods of pro- 7 iary wheel having a pivot element which may be inserted into the opening of any bracket to effect a detachable pivotal connection between the wheels, with the wheels in eccentric relation, the auxiliary wheel having a latch which engages another of the brackets, as the auxiliary wheel rolls on the ground, and as the auxiliary wheel moves toward concentric relation with respect to the main wheel, to lock the wheels together.

2. In a device of the class described, a main wheel having an opening, an auxiliary wheel, means for effecting a detachable pivotal connection between the wheels, with the wheels in eccentric relation, said means embodying a pin on the auxiliary wheel, received in the opening of the main wheel, and a latch on the pin, the latch engaging automatically with the main wheel to prevent withdrawal of the pin from the opening; and means for automatically locking the wheels together as the auxiliary wheel rolls on the ground, and as the auxiliary wheel moves toward concentric relation with respect to the main wheel.

3. In a device of the class described, main and auxiliary wheels, means for mounting the main wheel for rotation about a fixed axis, means for effecting a detachable pivotal connection between the wheels in offset relation to said axis of rotation of the main wheel, whereby as the main wheel turns about said axis of rotation, the pivotal connection will move in an orbit, thereby causing an elevation of the main wheel during a solely rotative movement of both wheels and while the'auxiliary wheel is moving to concentric relation with respect to the main wheel, and automatically-acting latch means on the wheels, coupling them together as they arrive at concentric relation to each other.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature.
